Abstract

Usage-dependent phenomenon has been commonly observed in computer information systems (CIS). Since the performance of CIS greatly depends on the phenomenon, how to model it is an important CIS design issue. A usage process model (the Simon-Yule model) for modeling the usage--dependent phenomenon is proposed. The model is modified and successfully applied to the performance evaluation of self-organizing linear search heuristics. Analytical and empirical results indicate that the model provides a realistic performance evaluation of the heuristics and presents a solution to the research open problems which have been unsolved for more than two decades. Furthermore, the results lead to develop a self-organizing mechanism incorporating the usage process model for continuous speech recognition systems in the artificial intelligence arena.
